[49.07] Galaxies and the IGM: Science Drivers for NHST

R.S. Somerville (STScI)

While the planned JWST telescope will open a window onto the very high redshift Universe, there is still much to be learned about galaxy formation and the IGM at z<6, where many informative features are readily observed in the UV or optical. I will discuss science drivers for a 4-10m class telescope with UVO multi-object spectroscopy and wide-field, high spatial resolution imaging, focused on studying key problems in galaxy formation and the interconnection between galaxies and the IGM. Specific topics will include the internal structure of galaxies and the cusp/angular momentum problem, the effect of supernova-driven winds on the IGM and later generations of galaxies, and the nature of the sources that reionized the Universe.
